The gemini SL3516 SoC has a crypto IP.
This serie had support for it.

Sorry I forgot to write it.
It was tested with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y.
Furthermore, it survives hours and gigs of write/read to a luks2 using xts(ecb-aes-sl3516).

I forgot also to write on performance, which is quite good.
On a luks2 partition (2To with bs=4096), a fsck comes from 14m26(without CE) to 8m48(with CE).
So it is really usefull.

With bs=512, the performance is similar with software.
